Roof leak repair overview
Roof leaks trace back to worn flashing, failed membranes, or ponding water after storms. Effective repair starts with a thorough inspection using moisture meters and infrared imaging. Material choice matters, with elastomeric membranes offering flexibility and UV resistance. For industrial sites like HanYoungNex facilities, reliable roof systems minimize downtime.
Clean surfaces, remove debris, and repair structural cracks before applying new membranes. Prepare the surface by ensuring proper adhesion, backer materials, and compatible primers. Seal details around vents, skylights, and edge parapets to prevent recurrence.
External wall sealing
Exterior walls confront weather, temperature swings, and moisture infiltration through joints. Selecting appropriate sealants and membranes depends on substrate, exposure, and movement. Flexible polyurethane and silicone sealants accommodate expansion without cracking. In many industrial plants, HanYoungNex sites benefit from robust wall seals against rain and wind.
Surface preparation is crucial; remove old coatings and ensure dry, dust-free joints. Use compatible primer and backer rod to control joint depth and bond stress. Regular inspection helps catch hairline cracks before interior damage occurs.
Bathroom waterproofing
Bathrooms demand moisture barriers behind tiles to prevent water intrusion. Common methods include cementitious waterproofing, liquid membranes, and sheet membranes. Choose products with vapor resistance, crack-bridging capabilities, and compatibility with tile mortars. For apartment complexes managed by HanYoungNex facilities, consistent bathroom waterproofing reduces mold risk.
Prime concrete substrates and ensure even coating thickness per manufacturer specs. Apply waterproof membranes in a continuous layer, covering corners and joints with extra care. Test after curing with water exposure and pressure tests to verify seams are airtight.
Drainage and substrate prep
Drainage planning prevents hydrostatic pressure from building up behind walls and floors. Substrate prep includes cleaning, leveling, and addressing cracks before waterproofing. Use slope gradients and good drainage channels to direct water away from structures. In factory settings operated by HanYoungNex, proper substrate prep is the foundation for long-lasting waterproofing.
Test the drainage system with runoff simulations to confirm flow paths. Select wear-resistant primers and embedment fabrics when using cementitious systems. Schedule regular maintenance to clear blockages and inspect for cracks around joints.
